Stainless Steel Modular Bathroom Floor Waterproofing System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bathroom floor waterproofing systems face challenges such as increased construction time, high personnel costs, difficulty in maintaining uniform quality, and the need for entire panel replacement due to thermal expansion differences and damage, especially in bathrooms with varying floor areas and completed walls.
Innovation Solution
A bathroom floor waterproofing system made of stainless steel, featuring a flat floor panel with integrated drainage units and side walls formed by bending a single stainless steel sheet, allowing for detachable coupling of multiple systems, which reduces replacement costs and time, and facilitates easy maintenance by allowing only defective panels to be replaced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single large waterproofing panel is used to cover the entire bathroom floor, then the waterproofing coverage is complete, but the storage and transportation volume is large and installation is difficult
Solution Approach 1:
The waterproofing system is divided into multiple detachable panels that can be assembled together to cover the entire bathroom floor. Each panel can be independently stored and transported, significantly reducing the volume requirements compared to a single large panel, while still achieving complete floor coverage when assembled.
2Area of stationary object
If a single large waterproofing panel is used, then the waterproofing coverage is complete, but the panel cannot be installed in bathrooms with completed walls
Solution Approach 1:
The waterproofing system is segmented into multiple smaller panels that can be maneuvered through doorways and installed in bathrooms where walls are already completed. The modular design allows installation in confined spaces without requiring removal of finished walls.
Solution Approach 2:
The detachable coupling mechanism allows the waterproofing panels to be flexibly assembled and disassembled, enabling installation in various bathroom configurations and accommodating situations where walls are already completed. The system can be adapted to different spatial constraints.
3Reliability
If the entire floor panel is replaced when water leakage occurs, then the waterproofing is restored, but the replacement cost and time are increased
Solution Approach 1:
The waterproofing system is divided into detachable panels, allowing only the specific panel with water leakage issues to be replaced rather than the entire floor covering. This significantly reduces both the time and cost of repair while restoring waterproofing functionality.
Solution Approach 2:
When water leakage occurs in a specific panel, only that defective panel is removed and replaced, while the remaining functional panels are retained and reused. This selective replacement approach reduces waste and minimizes replacement costs and time.
4Ease of manufacture
If thermoplastic resin material is used for the waterproofing panel, then the construction is simplified, but thermal expansion differences cause cracks
Solution Approach 1:
The material selection changes the thermal expansion parameter to match that of concrete floors. By choosing stainless steel or other materials with thermal expansion coefficients similar to concrete, the system maintains construction simplicity while preventing cracks that would otherwise result from differential thermal expansion.

AI summary
A bathroom floor waterproofing system includes: a flat floor panel made of stainless steel; at least one drainage unit provided at the floor panel; side walls formed by bending a pair of opposite edges of the floor panel upwards; and a fastening unit comprising a male fastening plate formed by bending one of the edges of the floor panel upwards so as to be perpendicular to the floor panel and a female fastening plate into which the male fastening plate of an adjacent bathroom floor waterproofing system is detachably fitted and coupled.
